Abstract: Because of existing defects such as hard work of caculating task, low accuracy of drawing, taking time and leasting effort in manually drawing construction documents of mining district station, the paper designed a construction documents drawing system of mining district station based on AutoCAD. It introduced structure, software design and characteristics of the system. The system adopts modularization programming method, which makes counting and drawing of district station line, chart of turnout distinction and yard tunnel to be finished by programming modular, so as to generate mining district station quickly by only inputting relevant parameters and increase working efficiency.
